Currently all tables are printed in statements like `DESC TABLES`, `DESC KEYSPACE ks` or `DESC SCHEMA`.
But when we create a table with cdc enabled, additional table with `_scylla_cdc_log` suffix is created.
Those tables shouldn't be recreated manually but created automatically when the base table is created.
This patch hides tables with `_scylla_cdc_log` suffix in all describe statements.
To preserve properties values of those tables, `ALTER TABLE` statement with all properties and their current values for log cdc table is added to description of the base table.
